To Edit Port Numbers for Instances Referencing a Configuration

Each instance referencing a named configuration initially inherits its
port numbers from that configuration. Since port numbers must be unique on
the system, you might need to override the inherited port numbers.

In the tree component, expand the Configurations node.

Select the node for a named configuration.

Select System
Properties.

The Admin Console displays the Configuration System
Properties page.

Click Instance Values next to the instance variable you want to
edit.

For example, if you click Instance Values next to the HTTP-LISTENER-PORT
instance variable, you see the value of HTTP-LISTENER-PORT for every server
instance that references that configuration.
